Error inflating class Android support design

Question

What I am trying to do is use the new android support design library mentioned here: http://android-developers.blogspot.com/2015/05/android-design-support-library.html.

Answer 1

This error can be caused due to reasons as mentioned below.

1. This problem will likely occur when the version of your appcompat library and design support library doesn't match.

Example of matching condition

  compile 'com.android.support:appcompat-v7:24.2.0' // appcompat library

  compile 'com.android.support:design:24.2.0' //design support library

2. Your theme file in styles should not have

   <item name="colorPrimary">#4A0958</item>
   <item name="colorPrimaryDark">#4A0958</item>
   

   It should look somewhat like this.

   <style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
   
    <item name="colorPrimary">#4A0958</item>
    <item name="colorPrimaryDark">#4A0958</item>
    <item name="colorAccent">#4A0958</item>
   
   </style>
   

Answer 2

I had the same issue. I resolved it build cleaning and rebuilding the project. When I ran it again, it had no such exceptions thrown.

Answer 3

If you are using any of the Design Library components, you should ensure your activity extends AppCompatActivity and uses an appropriate Theme.AppCompat theme. Note that the FloatingActionButton relies on the colorAccent set on your theme - ensure your theme has that defined.

If everything else doesn't work, Upgrade the version of the dependency and version. In your build.gradle file:

compileSdkVersion 24

compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.android.support:design:24.2.0'
compile 'com.android.support:recyclerview-v7:24.2.0'
compile 'com.android.support:cardview-v7:24.2.0'

I had the same error. After more Search i have got solution. Just Change build.gradle (Module: app)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24 // previous 23

    buildToolsVersion "24.0.2"

    defaultConfig {
        applicationId "com.ventrux.thevideoapp"
        minSdkVersion 15
        targetSdkVersion 24  // previous 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
    compile 'com.android.support:appcompat-v7:24.2.1'       // previous 23.2.1
    compile 'com.android.support:design:24.2.1'          // previous 23.2.1

    compile files('libs/YouTubeAndroidPlayerApi.jar')
}

Xml for FloatingActionButton

  <android.support.design.widget.FloatingActionButton
            android:id="@+id/fab"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|end"
            android:src="@drawable/plus_iconaddvideo"
            android:layout_marginRight="30dp"
            android:layout_marginBottom="30dp"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true"
            android:layout_alignParentEnd="true"
            android:layout_marginEnd="30dp"
            />
